busch jaeger smart home multi-sensor 2CKA006132A0331 — wired, measures light and motion, brightness 1–1000 lx, size 80×80×45 mm

The busch jaeger smart home multi-sensor 2CKA006132A0331 is a wired environmental sensor designed for integration into building automation systems. It measures indoor brightness in the 1–1000 lx range and detects motion to enable automated scenes, lighting control or security triggers. With compact dimensions of 80×80×45 mm, the unit is suitable for discreet wall or ceiling mounting in residential and commercial interiors where continuous, reliable detection of light level and presence is required.

Advantages

The multi-sensor combines light level measurement and motion detection in one wired device, reducing the need for separate sensors. Its measurement range from 1 to 1000 lx covers typical indoor lighting conditions from dim to bright, allowing accurate control of lighting and automated responses. The compact 80×80×45 mm enclosure simplifies installation in standard mounting locations without occupying excessive space. As a wired device, it provides a stable connection for continuous monitoring and integration into existing busch jaeger smart home installations.

Suitable for

• Automated lighting control in corridors, offices and living areas
• Presence detection to trigger scenes or HVAC adjustments
• Integration into security or building management systems for occupancy monitoring

Key specifications

• Sensor type: combined light and motion sensor
• Brightness measurement range: 1–1000 lx
• Mounting dimensions: 80 × 80 × 45 mm (W × H × D)
• Connection: wired for integration with building automation
• Installation: suitable for wall or ceiling mounting

How to use

Install the sensor in a suitable indoor location on a wall or ceiling where both light and occupant movement can be detected without obstructions. Connect the device to the building automation wiring according to the system installation guidelines and electrical safety rules. Configure the automation system to read brightness values and motion events from the sensor and assign actions such as switching lights, activating scenes or generating occupancy reports. Position the sensor to avoid direct glare or reflective surfaces that could affect brightness readings and to provide an unobstructed field of view for motion detection.

Usage recommendations

For reliable operation, place the sensor at a height and orientation that provide a clear view of the monitored area and keep it away from heat sources or direct sunlight. Use the sensor's brightness data to implement gradual dimming or daylight-dependent control and combine motion detection with time or presence logic to reduce false triggers.
